We explore the broadband excitation spectrum of bulk ${\mathrm{PtTe}}_{2}$ using electron energy-loss spectroscopy and density-functional theory. In addition to infrared modes related to intraband three-dimensional (3D) Dirac plasmon and interband transitions between the 3D Dirac bands, we observe m...
